On a machine I (tlous) have been given access to open a shell as another user (serviceAccount)
sudo su - serviceAccount has the desired effect of opening a shell as this serviceAccount user. So far so good.
This is nice, but I want to run a command as this user without opening a shell.
Let's say the command is
sudo -u serviceAccount whoami
Sorry, user tlous is not allowed to execute '/usr/bin/whoami' as serviceAccount ...
sudo su - serviceAccount -c whoami
Sorry, user tlous is not allowed to execute
'/bin/su - serviceAccount -c whoami' ...
And other variations. What am I missing? Can this be done in a oneliner? The reason is that I actually want to run this as an ssh command:
ssh -t email@example.com sudo su - serviceAccount -c whoami
